I have read the documents obout aterisk.I wonder the requirements on installing asterisk besides software package. whether we can set a telephony system with Phones (hardware or software) and Linux system and a ethernet card on internet?
i won’t even try to answer your question, but just wanted to say that maybe, as english wouldn’t appear to be first language, you should post your question in your preferred language.
the people that post here are a pretty diverse lot and there’s likely to be someone who can help you.
I am not 100% sure what you are asking, but let me take a crack:
If you want to set up asterisk, and have incoming VOIP service, and want to use VOIP softphones or IP hardware phones, you simply need a server with a network card.
However, if you want an incoming PSTN (regular phone line) for incoming calls, and/or want to connect standard phones to your system, you will need to purchase additional hardware like the boards offered by Digium (digium.com).
Does that help?
At first i want to extend my thanks to you for your help ,meanwile i feel so sorry to exhaust you because of my not very well english.But i will try my best let you catch what i said.
I mean that whether it is true that if I only want to telephone each other with IP hardware through internet,i only need a asterisk server with network card and if i want to comunicate with PSTN user, i should have another card just like the boards offered by Digium. If it is true that i should have another card like boards offered by Digium,which replacement can be found in china market?
thanks a lot!
With best regards!
